l'iill -wh'om it may concern I -Be known that I, FREDERICK E. GOLD-sMrrH, a citizen of the United States, and a resident of Middletown, inthe county of Butler and St-ate of Ohio, have invented a new and useful"Machine for Coating, of

which the following isla specification.

My invention relates to machines for supplying" coating 'to objectssuch, for example,

ple and -'e' zonoinica'lly built machine for desinated; n

lecliaracteristics andxadvantages of the invention are hereafter pointedout in detail in connection with the accompanying drawing, which showsin diagrammatic form an exe-mplifying'structure in which thesaidinvention i'stmbodied;

The coating roll is rotated from any suitable source of po'wer,'or powermaybe applied to gear 13 or shaft of the pressure roller. Rotation ofthe shaft of coating roll 7, for example, transmits motion to gear 13thence through -idle pinion 14 to shaft of pressure roller 8. Theadjacent surfaces of the coating roll and pressure roller therefo1'erotate in the same direction, as indicated 'by the arrow. The feed beltand the carry-off belt are simultaneously driven by Specification. of(Letters Patent. ,P Application filed July 26, 1906. Serial K013279253the shaft; veniently exterior certa t 28,1912.

r adj ustabl on a pivotal mounting such'as 29.

In operation, movement of the pitman 25' causes the frame 28 tooscillate in the tub.

The agitator blade moves continuously the coating material, serving tostir and scrape thesame thoroughly .away froni the bottom of .the tubandto keep the material in proper condition for use. The scoop 27performs," also a similar function. At eac'lf forward stroke the scoop 27carries a quantity of coating material, and on encountering the lowerface of plate-28. (-theplate-antl scoop being shaped so as tocooperateto produce the desired result) this material'issqueezed orsquirted out intotrough 20. The coating roll 7 is provided with abucketed, pervious or absorbent surface and this surface is alsopreferably compressible or elastic. In rotating the coating roll comesin contact with the coating material in the trough and carries thismaterial up and into contact with the lower surface of the biscuit asthey pass, applying to them an even coat of the material. Surpluscoating material in trough 20 runs out at the ends and top of the troughback into the tub 21.. It is preferred that the proportions of scoop 27or its rate of motion be such that a considerable excess of coatingmaterial is delivered into the trough over what is immediately used.This insures a copious circulation of coating material and keeps thesame in the best condition for use: The shape of the plate 28 and scoop27 may be widely varied to meet different conditions. By changing theshape of scoop 27 slightly and making its discharge point somewhathigher than that shown in the drawing the plate 28 may sometimes beomitted and the coating material may spill from scoop 27 into trough 20.

The features of this invention, and especially the means ofsupplyingcoating material to the roll, I believe to be broadly new with me, and Ido not limit myself'in any respect to details.

I contemplate any changes which may be made within the spirit and scopeof the invention.

IVhat I claim is:

1. In a machine for coating, a coating roll, feed and deliverymechanism, a receptacle for coating material, and a scoop moving be lowsaid mechanism for supplying coating material to the roll.

2. In a machine for coating, a coating roll, a receptacle for coatingmaterial, a trough below the roll, and a scoop for carrying coatingmaterial from the receptacle and depositing it in the trough.

3. In a machine for coating, a coating roll, a receptacle for coatingmaterial, a scoop, means for moving said scoop into and out of thereceptacle, and a plate cooperating with the scoop to supply saidcoating material to the roll.

4. In a machine for coating, a coating roll, a trough below the roll, areceptacle for coating material, a scoop arranged to oscillate insaidreceptacle, and a plate cooperating with the scoop to depositcoating material in the trough.

5. The combination of a coating roll, a tub, a frame mounted tooscillate in the tub, a trough beneath the coating roll, a scoop on theframe, a plate cooperating with the scoop to deposit coating material inthe trough, and means for oscillating the frame.

6. The combination of a coating roll, a tub, a frame mounted tooscillate in the tub, a trough beneath the coating roll, a scoop on theframe, an agitator blade on the frame, a plate cooperating with thescoop to deposit coating material in the trough, and means foroscillating the frame.

7. In a coating'machine, the combination of a coating roll, a troughbeneaththe roll, a tub below the roll and trough for coating material, apivotally mounted. plate adjacent to the trough, and an oscillatingscoop serving to raise the coating material from the tub and dischargeit into the trough by contact with the plate.

8. In a coating machine, the combination, of a coating roll, a trough, atub for coating material having a cylindrical inner surface, a shaft, ascoop carried by the shaft serving to elevate coating material from thetub and discharge it into the trough, and an agitator carried by theshaft and moving in close proximity to the surface of the tub.

9.'In coating mechanism, the combination of a coating device, acontainer adapted to retain coating material adjacent to said. device, areservoir below the coating device, a conveyer for movin coatingmaterialfrom the reservoir to sai container, and means for raising and'loweringthe reservoir to clear it from said coating device and conveyer forplacement and replacement.

In'testimony whereof I have affixed my signature in the presence of twowitnesses.
